Comet 46P/Wirtanen

I caught Comet 46P/Wirtanen in one 240-second exposure as it was passing through the constellation Eridanus. Next week 46P will pass about 7.2 million miles (0.0774 AU) from Earth, it's closest approach for the next 20 years. William Optics GT81, ZWO ASI071MC camera, Orion Atlas EQ-G
